Reorganize and consolidate documentation into structured `/docs` directory for better navigation and maintainability. New documentation structure: - docs/README.md - Documentation hub with complete index - docs/getting-started/ - Installation and quick start guides - docs/development/ - Workflow and testing guides - docs/archive/ - Archived PHASE_*.md completion summaries Key changes: - Created docs/ directory with 9 subdirectories - Moved HEADLAMP_INSTALLATION.md → docs/getting-started/installation.md (streamlined) - Created docs/getting-started/quick-start.md (5-minute tutorial) - Moved DEVELOPMENT.md → docs/development/workflow.md - Moved TESTING_GUIDE.md → docs/development/testing.md - Archived 12 PHASE_*.md files to docs/archive/ - Updated CHANGELOG.md with v0.2.0 details - Created main README.md with badges and links to docs Benefits: - Clear documentation hierarchy by user journey - Easier navigation with centralized docs/README.md index - Reduced clutter in repository root - Improved cross-referencing between documents - Better onboarding for new users and contributors Phase 1 deliverables (1-2 days estimated, completed): ✅ Organized docs/ directory structure ✅ Consolidated installation guides ✅ Streamlined development documentation ✅ Updated CHANGELOG to v0.2.0 ✅ Archived phase completion files ✅ Created documentation hub ✅ Updated main README with navigation ✅ Fixed cross-references Next: Phase 2 - API documentation with TypeDoc Generated with [Claude Code](https://claude.ai/code) via [Happy](https://happy.engineering) Co-Authored-By: Claude <noreply@anthropic.com> Co-Authored-By: Happy <yesreply@happy.engineering>
